I have created a 10 Gigapixel Ulam spiral... that means the numbers 1 to 10,000,000,000 are represented. It's huge but viewable using HD View from Microsoft... which should run on most operating systems and browsers.

From a distance the spiral looks quite featureless, click here to start zoomed into the centre of the spiral... you can zoom using the buttons on the top right, or the scroll wheel on your mouse. Click and drag the image to move in any direction.

My latest software release on this page includes information about how this image was created.
